Extra-Planetary Anomaly - Asteroid
Scan this asteroid to find a Beryllium Deposit.
Extra-Planetary Anomaly - Angaran Satellite Navpoint
After completing the quest "A Trail of Hope" you’ll be able to talk to Maariko on Aya, who will give you this quest. Scan the first Angaran Navpoint Anomaly in the Onaon system to gain 50 Remnant Research Data points.
This nearly-habitable planet houses a concealed Kett satellite. Do the Angara a favor and disable this thing, while also earning yourself 50 Heleus Research Data points.
Despite their best efforts, the Angara have not yet mined this planet dry, as evidenced by the Graphite Deposit you can find on its surface.
